Abstract (en)

Disclosed is a working contact cooling system for a high-power device (1), wherein the sealed case body (8) is a structure having inner and outer layers, a chamber between the inner and outer layers is filled with a heat-superconductive coolant (9), and an outer wall of the outer layer of the sealed case body (8) is provided with heat dissipating fins (10); the sealed case body (8) is provided with an insulating liquid heat-conductive coolant (2), the coolant pump (6) sinks in the insulating liquid heat-conductive coolant (2), the filter (7) is installed at an inlet of the coolant pump (6), the coolant pump (6) is connected to the spray main pipe (5), and a plurality of spray branch pipes (4) are connected in parallel with the spray main pipe (5), each of the spray branch pipes (4) is provided with a plurality of nozzles (3), and the nozzles (3) face the high-power device (1); the nozzles (3) spray against front and back surfaces of the high-power device (1) to form a relatively open spray structure; the insulating liquid heat-conductive coolant (2) is a non-polar substance, and the insulating liquid heat-conductive coolant (2) has no phase change during the spraying process. The present invention has reasonable heat dissipation structure and effective heat dissipation.
